HEAT DISTRIBUTER AND EQUALIZER FOR COOKING-STOVES.

Specification of Letters'Patent.

Patented Feb. 29, 1916.

Application filedlanuary 13, 1916. Serial No. 71,841.

To all whom it may concern:

Be it known that 1, JOHN L. CARTER, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certainv new and useful Improvements in Heat Distributors and Equalizersv for Cooking- Stoves, of which the following is a specification.

The invention pertains more particularly to a novel structure to be placed on the top of a' cooking stove to receive thereon vessels in which food is to be cooked or water or the like boiled and which structure serves to distribute and equalize the heat at the bottoms of such vessels and prevents the flames and direct heat from impinging against the same. With the use of my invention, the cooking may be efficiently performed, the danger of burning or scorching the food is greatly lessened and the cooking-vessels are protected against destructive action of the flames.

The structure of my invention will preferably be formed from one integral piece or plate of sheet metal folded to afford a proper base to rest on a stove and suitable supports to receive the cooking utensils and also suitable heat equalizing and distributing chambers, all as hereinafter described in detail.

Referring to the accompanying drawings: Figure 1 is a top view of a structure embodying my invention; Fig. 2 a sectional view of the same taken on the dotted line 2-2 of Fig. 1; Fig. 3 a sectional view of the same taken on the dotted line 33 of Fig. 1; Fig. 4 an enlarged sectional view through a portion of the same; Fig. 5. a sectional view illustrating a modified form of my invention, and Fig. 6 is a further sectional view illustrating another modified form, of my invention.

The structure of my invention may for convenience be termed a plate, and this plate is formed by bending a sheet of metal of ap-;

propriate size into corresponding base members 10 to rest on a stove, upper members 11 affording a support for the cooking vessels, return members 12 above said base members and extending over flame apertures 13 therein, and members 14 connecting said return members and superposed above and spanning the space between the adjoining edges of the same.

In the formation of the platecommencing,

say, at the left hand side of Fig. 3, a, portion of the sheet is left to constitute a portion of a horizontal member 14, and thereupon the sheet is bent downwardly and then toward the left suitably below said member 14 to form the return member 12, whence the sheet is bent downwardly and then horizontally toward the right to form a base member 10, at whose right hand edge the sheet is bent upwardly and then downwardly to create a support 11, and then the sheet is bent horizontally toward the right to form another base member 10 and then upwardly and then toward the left to create a return member 12, at whose left hand edge the sheet is bent upwardly and then toward the right to form a connecting member 14 and then downwardly and then toward the left to provide another return member 12, whence the sheet is bent downwardly and then toward the right to form another base member 10 and then upwardly and then downwardly to create another vessel support 11, whence the bendings of the sheet are continued to form as many additional members 10, 12, 14 and 11 as the desired dimensions of the plate may require. Between the base members 10 and return members 12 are formed channels 15 for the flow of the heat along the length of the plate and between the return members 12 and top members 14 are formed further heat channels 16, these being above the channels 15, and between the adjacent ends of the members 12, 14 are formed channels or passages 17 which are adjacent to the supports 11 and open from the heat channels 15, said passages 17 serving to direct the heat issuing from the channels 15 upwardly along the vertical portions of the supports 11 and to the cooking utensil which may be resting on the supports 11. The apertures 13 in the base members 10 are below the return members 12 and out of the vertical plane of the passages 17, and hence flames and heat of undue intensity ascending through the apertures 13 will strike the lower surfaces of the return members 12 and be by them directed horizontally and laterally, so that the proper heat will escape upwardly through the passages 17 and against the cooking utensil that may be on the supports 11. The air within the channels 16 becomes heated, and hence the top members 14 are kept hot and the heat radiating therefrom assists in the cooking.

My inventlon has for its purpose to dis-.

tribute and equalize the heat arising from the stove and to protect the cooking utensils against destructive action of the flames and heat of the stove, and these purposes are accomplished by the plate illustrated in Figs. 1'

to 4 inclusive.

The bendings of the sheet metal to form the plate of my invention and the location of the heat apertures 13 may be modified, and hence in Fig. 5 I illustrate a construction exactly the same as that shown in Fig. 4 with the exception that the heat apertures are located in the return members, as at 18. In the use of the plate having the apertures 18 in the return members, the heat descends into the channels 15 and finally reaches the passages 17 and ascends along the sides of the support 11.

In Fig. 6 the modification resides in forming extended surfaces 19 for supporting the cooking utensils and in locating some of the inlet apertures for the heat and flames in the base members of the plate and others in the return members. The extended supporting surfaces 19 for thecooking utensils are at the upper ends of the vertical members 20, as clearly shown, and their presence creates additional passages 21 between the top members 22 and the bottoms of the supports. The members 22 correspond with the members 14 of Fig. 3, and since Fig. 6 shows a modification, I number the return members 23, the base members 24 and the inlet apertures for heat 25. struction shown in Figs. 1 to 4 inclusive, since in many instances it is desirable that the supports for the cooking utensils be narrow at their upper edges.

In all the forms of the invention hereinbefore described, the sheet of metal is folded to form the long channels, as 15, 16, with the top members 14 and return members 12 separated from the utensil supports sufliciently to form the passages 17, and in each form of the invention the heat inlet apertures or holes, as 13, have over them horizontal members which serve to deflect the heat and flames and prevent the flames and intense heat from passing directly into contact with the utensils which may be placed upon the plate.

I am aware that the sheet of metal may be folded in other ways to create long channels and provide members to prevent the flames and intense heat from striking the cooking utensils, and therefore I do not limit the invention to the precise bendings of the sheet of metal hereinbefore described. I have however shown in the drawings the preferred embodiments of my invention and I have found that in practical use the construction shown in Figs. 1 to 4 inclusive is of very great efliciency.

The plate hereinbefore described has been referred to as a top plate for stoves. It is Copies of this patent may be obtained for five cents each, by addressing the I prefer the cone stove as distinguished from employing it as the bottom plate for a portable oven.

What I claim as my invention and desire to secure by Letters-Patent, is:

1. A heat distributer and equalizer for cooking stoves, comprising a folded plate of sheet metal affording base members, vertical supporting members extending upwardly between said base members, horizontal connecting members at the sides of said vertical members and spaced therefrom to form heat passages, and return members between said base members and connecting members and spaced therefromto form heat channels at the sides thereof, flame or heat openings being formed in some of said members below said connecting members.

2. A heat distributer and equalizer for cooking stoves, comprising a folded plate of sheet metal affording base members, vertical supporting members extending upwardly between said base members, horizontal con necting members at the sides of said vertical members and spaced therefrom to form heat passages, and return members between said base members and connecting members and spaced therefrom to form heat channels at the sides thereof, flame or heat openings being provided in said base members below said return members and out of the vertical planesof said heat passages. g

' 3. A heat distributer and equalizer for cooking stoves, comprising a folded plate of sheet metal afiording base-members, utensil supporting members, and horizontal members above said base members andspaced.

therefrom to form heat channels and also spaced from said supporting members to form heat passages, said base-members having openings therein.

4. A heat distributor and equalizer for cooking stoves, comprising a folded plate of sheet metal affording basemembers, utensil supporting members, and horizontal members above said base members and spaced therefrom to form heat channels and also spaced from said supporting members to form heat passages, said base-members hav ing openings therein below said horizontal members and out of the vertical planes of said heat passages.
